【题目】生产小组加工一批零件,原计划用14天,平均每天加工1500个,实际每天加工零件比原计划每天加工的多2/5,实际用了多少天就完成了任务? 【分析与解】一、从整数的角度思考解法一根据已知条件,先求出计划加工零件的总个数和实际每天加工零件的个数,再求实际加工零件的天数.即: 【Subject】The production team processed a batch of parts. The original plan was to use 14 days, with an average of 1500 processings per day. The actual daily processing of parts is 2/5 more than the original plan. How many days actually used to complete the task? Solution 】 First, consider the solution from the perspective of integers. First, according to the known conditions, first calculate the total number of parts of the planned processing and the actual number of parts processed each day, and then find the number of days actually processed parts. That is:
